Unicompartmental knee arthroplasty (UKA) is considered the treatment of choice in patients with single compartment arthritis
of the knee at early stages or with osteonecrosis limited to one compartment. However, results in the literature are still
controversial and it is a technically difficult procedure. The main goal of UKA is to restore the articular space of the afflicted
compartment, without influencing the limb alignment. Selection of patients and pre-operative planning are crucial. The necessity
to improve functional results and to reduce immobilization of the patients has led to the development of minimally invasive
surgery. Applied to UKA, this approach reduces blood loss and surgical time, causes fewer symptomatic postoperative complications,
and permits earlier recovery compared to the traditional incision. The shorter incision makes careful pre-operative planning
essential. We briefly review the indications for UKA, the pre-operative clinical and radiological assessment, and the surgical
procedure.

Lesions of cortical areas 17 and 18 were produced in newborn kittens by local injections of the excitotoxin ibotenic acid. In the adult this results in a microcortex which consists of superficial layers I, II and III, in the absence of granular and infragranular layers. Horseradish peroxidase, alone or wheat germ agglutinin conjugated, was injected in the microcortex or in the contralateral, intact areas 17 and 18. The microcortex maintains several connections characteristic of normal areas 17 and 18 of the cat. It receives afferents from the dLGN, and several visual areas of the ipsilateral and contralateral hemisphere. However, it has lost its projections to dLGN, superior colliculus, and, at least in part, those to contralateral visual areas. Thus some parts of the microcortex receive from, but do not project into, the corpus callosum. In addition, the microcortex maintains afferents from ipsilateral and contralateral auditory areas AI and AII which are normally eliminated in development. 相似文献

In situ saphenous vein grafts are being used with increasing frequency for bypass procedures involving the femoral and popliteal arteries. Complications of these procedures include anastomotic stenoses and persistent arteriovenous fistulae that may result in failure of the graft. Balloon angioplasty and embolotherapy with detachable balloons were employed successfully in three or four recent cases of patients with complications from in situ grafts. Tailored angiography is essential for evaluating in situ grafts, and interventional techniques are extremely useful for managing complications. 相似文献

PURPOSE: The purpose of the study was to evaluate the incidence of incontinence pad use among patients admitted to medical wards, the reasons why nurses decide to use an incontinence pad, the extent to which the use of pads is avoidable, and the outcome of inappropriate pad use after discharge from the hospital. METHODS: A prospective cohort study was conducted; patients admitted to medical wards were observed during hospitalization and a 7-day follow-up period after discharge. SUBJECTS AND SETTING: The study was conducted in 2 acute-care units in Northern Italy. All new patients admitted to the units were recruited. RESULTS: At the time of admission to the hospital, in addition to the 120 patients who already used incontinence pads, there was a 34% incidence of new cases (98/286). The most frequent reason why nurses decided to use this aid was incontinence caused by space-time disorientation, followed by limited mobility, incontinence, patient request, nursing shortage, and involuntary urine leakage not perceived by patient. Seventy patients out of 208 used incontinence pads unnecessarily for a total of 544 days. CONCLUSIONS: Decisions about the use of the incontinence pads are not always consistent with research-based or literature-based suggestions. Nurses should develop clinical guidelines or protocols for the appropriate use of incontinence pads. 相似文献

A platelets count was performed on 100 subjects using both the electronic counter and a manual method; the results obtained concerning healthy subjects are overlapping. In subjects with structural alterations regarding platelets and red blood cells, the electronic counter method has overestimated the number, yet making note of it. 相似文献
